本研究提出一個考量同步生產下的單一模式生產線平衡之型二問題(Type II of single-model assembly line balancing problem by considering concurrent engineering, T2PwithCE)模式，本模式將同步工程的哲理導入生產線平衡問題之中，其主要目標在於改善整體生產線的生產效率。在未將平行工程的概念導入前，若工作站內的工作單元可同時且同步運作時，其生產週程時間的估算方法明顯將導致整體生產率的低估，因此，傳統設計易造成資源浪費與閒置。早期在處理有關同步工程與生產線平衡問題乃是一件困難的事，但透過本研究所提之四位置編碼技術(Four-Position Coding Technique, FPCT)，可以使同步生產的情況經由對工作單元的編碼來進行探討，並藉由FPCT編碼使有關討論同步生產的生產線平衡問題可無礙地在LINGO 9.0軟體上執行與求解。 本模式乃藉由數值範例模擬在不同的給定工作站數下求取最佳的生產週程時間，並規劃出各工作站佈置的最佳解，因此本研究乃屬於動態的型二問題(Dynamic Type II Problem)。另外，本研究亦提供了一套具備了高度的可重複性且完善的研究流程，並將考量同步後之生產效率與傳統生產線平衡模式進行比較，最後更進一步依照數值模擬的結果將不同各工作站數要求下之工作站佈置情況編製成生產線佈置決策分析表(Decision Support Table for Assembly Line Layout, DSTforALL )，並嘗試開發一套決策支援系統(Decision Support Systems, DSS)檢核表，當可用空間的大小與尺寸、訂單的訂購數量與交貨時間已知的情形之下，可藉由此系統以快速得出最佳的生產週程時間與工作站佈置情形，綜言之，本研究將同步生產的觀念導入生產線平衡的型二問題中，為生產線設計佈置者提供一個更近實務的佈置理念。 This study proposes a type II single-model assembly line balancing problem in considering the concurrent engineering (T2PwithCE). The proposed model applies to the theory of concurrent engineering into the assembly line balancing problem, and then aims to improve the production rate. For traditional balancing method the cycle time of the assembly line will obviously underestimate. Considering concurrent engineering into the assembly line balancing problem is a complicated job, but such a hard work can be done through the proposed coding technique “Four-Position Coding Technique (FPCT)”. In addition, this study applies the LINGO 9.0 Extended Version to solve a complicated issue. This paper is to find out the optimal number of workstations for a given exemplified case and to determine the layout in every workstation. The simulated analyses for various numbers of workstations are conducted, and then both the optimal number of workstations and cycle time are determined. In addition, this study has also provided repeatable research procedure, as well as compared the production rate of proposed method to traditional method with concurrent engineering. The result of given numerical simulation for workstation layout in different number of workstations can be formed a Decision Support Table for Assembly Line Layout (DSTforALL) and a decision support system (DSS) examined table is established. From decision support system, a given available space, size, order quantity and due date, then a can be referred quick workstation layout.
